Paris to Set Default Citywide Speed Limit Below 20 MPH

Slow-speed zones are an increasingly widespread tactic to improve street safety and urban livability. Inspired by a German town that limited motor vehicle speeds to 30 kilometers per hour — or roughly 19 miles per hour — British activists have made 20 mph zones a core street safety policy across the nation.  The movement has begun to catch on in the United States, where New York City has been implementing 20 mph zones on neighborhood streets.
